Extraction of non-labeled and 15N- and 15N/13C-labeled PCB from Synechocystis cells. Photographs (A) and absorption spectra (B) of PCB extracts for each PLE. (C) HPLC chromatograms of absorbance at 660 nm are shown for the prewash at 75�C and the 1st, 2nd and 3rd extractions from non-labeled cells at 125�C. MS of C3-E PCB (upper) and C3-Z PCB (lower) prepared from non-labeled (D), 15N-labeled (E) and 15N/13C-labeled (F) cells.
